Title: Valve system for internal combustion engine
Inventor: CHOKAI MAKI
IPC: F01L3/10
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To improve valve follow-up ability and reduce incurring of a friction loss, in a device wherein a valve lift amount is switched in a two-stage by a variable valve system. SOLUTION: The spring constant of a valve spring is changed in three stages along with displacement thereof and has two bending points (point c and point b). A spring constant in a range wherein displacement is lower that in the point (b) corresponding to a maximum lift amount of a low speed type cam is lower than a spring constant in a lift amount larger than the aforesaid spring constant. Even when a spring load in a point (a) corresponding to a maximum lift amount at a high speed type cam is set to a high value, a spring load in the point (b) is reduced and incurring of a friction loss is reduced.
